Intel Q9450 vs Phenom 9850 - ATI HD3870 X2

[gosh]

Question: Is there information about the difference in latency reading and writing data comparing Hypertransport and the Front Side Bus?
Hypertransport is designed to be a very fast point to point communication (if I am right). If this communications is very fast it could be one explanation why AMD is even or sometimes have a bit better numbers on some tests when they test single threaded games on very high detail and high resolution.
If communication to external hardware is similar on AMD and Intel then Intel should always win ins single threaded games if they are clocked the same even if the main bottleneck is the GPU. 6 MB L2 cache at 15 clocks that can be used for one core compared to 512 KB L2 cache on AMD does make a huge difference (I think more than 10% in all single threaded games) if processor performance are compared.
